This invention relates to decalcomania transfers and is particularly useful in connection with revenue stamps and the like.

A primary object of the invention is to provide a decalcomania transfer with a distinctive mark or design which under ordinary conditions is practically invisible but which can be detected When the transfer is held toward the light. @ther objects and advantages will appear as the specication proceeds.

The linvention is illustrated, in its preferred embodiment, in the accompanying drawing, in which:

Figure l is a diagrammatic view of a transfer embodying my invention. the various lavers making up the transfer being shown in separated relation and the spaces therebetvveen being greatly exaggerated: Fig. 2. a plan view of the paper sheet with the distinctive or identifying design applied thereto but the final lavers of the transfer body being omitted: and Fig. 3, a planview of the iinished article consisting of a series of transfer bodies applied to the base sheet. l

lin the illustration given, a strip or sheet d of water-permeable paper is surfaced on one side with a Water-soluble adhesive. A series of spaced transfer 'bodies are built up on the adhesive surfaee by printing successive layers of translucent ink or other suitable material. rllhe lavers of translucent ink are indicated on the drawing by the letter MW.

ln accordance with my invention. after several lavers of ink have been deposited as a foundation for the transfer bodies. l print or otherwise form upon the topmost layer W as Well as upon the exposed surface of the adhesive-covered paper a distinctive design or mark or print. After the identification design has been formed, the printing operation is continued until a number of successive layers of white translucent ink or the like print Which, by Way of example, may be a revenue stamp design.

The prominence of the identication design, the number and character of the layers W, and the character of the final top print are all coordinated so as to practically conceal the identification design When the transfer body rests upon the paper sheet or upon any ordinary background. However, when the transfer body is held up to the light, the @il identification design becomes distinguishable.

ln forming the transfer body, any ordinary or suitable transfer ink may be employed Such inks are ordinarily made by combining zinc oxide, White lead, or titanium oxide with @5 linseed oil varnish or the like. Sometimes a color dye is added to form diii'erent shades of White.

ln the operation. of applying transfer bodies of the character illustrated, usually 'adhesive remains to the bottom-most layer W to .fasten the. transfer body to the new surface.

One diculty experienced in the use of revenue stamps has been that such stamps readily become detached from cellophane, Wood boxes, etc., and have been repeatedly reused. The present form of transfer bod) readily adheres to cellophane, Wood, tin and paper containers and is too fragile in construction to permit removal and reuse. rllhe i identification design permits the spurious and counterfeit stamp to be readily detected by m the tax examiner, While at the same time it 1s effectively concealed under ordinary conditionsof use.

The identification design, as illustrated in the drawing, extends not only between certain of the successive layers W but also upon the .adhesive surface between the transfer bodles. This'enables the paper strip, with its series of transfer bodies, to be detected as genuine. At the same time, when the paper strip is dipped in Water, the design disappears as the adhesive goes into solution in the Water.V It Will be understood, however, that my invention may be employed Without exposing any portion of the design outside of the transfer bodies. Also, it will be understood that in the use of the Word translucent in the appended claims, I mean any White or other translucent material, through the strata of which the identifying mark may be rendered visible when the transfer body is held toward the light and invisible when the body is provided with an ordinary non-brilliant background.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in View of the prior art.

li claim:

l. A decalcomania transfer comprising a body built up of non-separable layers of translucent transfer ink, an identifying print on one of the intermediate inl; layers, a final print on the top of said body, and an adhesive layer on the exterior surface of the bottom-most ink layer for fixing the said transfer on a surface.

2. A decalcomania transfer comprising a body made up of non-separable layers of translucent transfer ink, a final print on the top of said body, adhesive on one side of the body for fixing the transfer to a surface, and a print on one of the intermediate ink layers visible by transmitted light to identify the layer-built transfer.

3. A decalcomania transfer comprising a plurality of non-separable layers of translucent material, a final print on an outer layer, adhesive on one of the outer layers for fixing the transfer to a surface, and a print on an intermediate layerv visible by transmitted light to identify the transfer.
